Sƒ21 cells were grown in TiterHigh Sf Insect Medium and the leading copetitor's medium in shaker flasks, at 27° C with a shaker speed of 130 rpm. As is shown, TiterHigh Sf supports much higher viable cell densities than the competition.

Sƒ21 cells grown in TiterHigh Sf Insect Medium and the leading competitor's medium were infected with a recombinant baculovirus expressing b-galactosidase. Cells were infected at a cell concentration of 1x106 cells per mL, with a multiplicity of infection of 5 virus particles per cell. Enzyme levels were measured at days 2, 3, and 4 post-infection. As is demonstrated, TiterHigh Sf beats the competition in terms of per cell baculovirus productivity.
